There are three modes of heat transfer: conduction, convection, and radiation. Any energy exchange between bodies occurs through one of these modes or a combination of them. Conduction is the transfer of heat through solids. Convection uses the movement of fluids to transfer heat. Heat radiation is the transfer of internal energy in the form of electromagnetic waves.
